“Lucky Strike Extra” … say,what?

November 26, 2014

Yipes.

In class,  I inadvertently dropped a phrase that revealed either my Midwest roots or my “maturity”, or both.

I referred to something as a “Lucky Strike Extra”.

You know, something out of the normal routine … an added benefit.

Most of the class ignored the comment and  some rolled their eyes.

But, one student emailed me:

“I have noticed you use the expression “lucky strike extra” in class — this is an old family favorite (we call extra “freebie” birthday/Christmas gifts lucky strike extras). It is not something that you hear all that often – it inspired some sentiment just in time for the holidays.”

That got me wondering where the phrase originated.

Here’s the back story ….

Gotcha: This is an unrecognized computer …

November 25, 2014

If you do any banking online, you’ve probably gotten that message at one time or another.

Maybe it was when you got a new computer … or, when you used a friend’s computer to pay a bill.

You probably didn’t think much of it.

You just answered the security questions and paid your bill.

Bet you didn’t stop to wonder: How did Bank of Boise know that this wasn’t my usual computer?

Better yet, ask: How does the bank know when I am on my regular computer?

Well, now that I’ve aroused you curiosity, the answer is ….

Your computer has its own distinctive “device fingerprints” that make it identifiable on the Net as your computer.

I worry about stuff like this.  So, I’d thought about this one.

And, my thinking was wrong.

Here’s what’s going on …

What the hell is a “devil’s advocate”?

November 24, 2014

This came in this week in class … subject was “confirmation bias” … how people naturally lock onto beliefs and only seek or notice that aligns with their going-in position.

One of the antidotes is enlisting a so-called devil’s advocate” to keep things honest.

A what?

You know, we’ve all been there …

You’re in meetings pitching an idea when some jabrone pipes in:

“Let me play the role of devil’s advocate …”

He then blasts your idea with half-baked criticisms.

As you aggressively defend your cherished idea, he backs off:

“Hey man, I’m just playing devil’s advocate”.

“Say, what? You mean your  just made up those cheap shots?”

I’ve been reading books on decision making this summer.

A couple have praised the use of so-called devil’s advocates to validate ideas and arguments.

Here’s what they’re talking about …

Uh-oh: Most published research findings are false…

November 21, 2014

I didn’t say it, the New Yorker magazine did, setting off a buzz in the halls of academia.

The theme of the New Yorker article –- titled “Truth Wears Off” –was that most (academic) research was flawed and not able to be replicated.  This is, the results were at best true under some special circumstances at a specific point in time, but can’t be replicated. At worst, they’re just plain bull.

Hmmm.

Challenging the integrity of publication-driven academics?

Turns out that the New Yorker wasn’t the first mag on the beat.

Weird poll results … explained by the “power of free”.

November 20, 2014

 

This was a wild week for ObamaCare.

First, there’s the steady stream “You’re stupid, America” videos from Prof. Jon Gruber.

Then, the 2nd Annual Open Enrollment period started for the Federal Health Insurance Exchange.

No big news there.

But, the combo of Gruber and the Open Enrollment, got the pollsters springing into action … with the politicos spinning like tops.

A couple of Gallup polls made news … with seemingly contradictory results.

The first was headlined:

=====

The second poll reported that moe than 70% of the folks who got their insurance through the Federal Exchange rated it as “good” or “excellent” …

Seems contradictory, right?

Is it 37% or 70%?

Let’s drill down a bit to reconcile the numbers …

Amazon and the “power of free” …

November 19, 2014

Everybody knows that Amazon’s free shipping program has been a resounding success.

So much so. that the company has announced that it will be moving the minimum qualifying order up from $25 to $35 … inducing shoppers to fill  their carts fuller or switch to the highly profitable Amazon Prime program.

The free shipping program’s success was highly predictable based an an apparently inadvertent “matched market test” that Amazon did.

It’s those shades of gray that are keeping you from making a decision …

November 18, 2014

Excerpted fro WSJ: Why So Many People Can’t Make Decisions

Some people meet, fall in love and get married right away. Others can spend hours in the sock aisle at the department store, weighing the pros and cons of buying a pair of wool argyles instead of cotton striped.

Indecisive Man

Seeing the world as black and white, in which choices seem clear, or shades of gray can affect people’s path in life, from jobs and relationships to which political candidate they vote for.

Have you even looked at YOUR health insurance premiums?

November 17, 2014

This headline in the NY Times caught my eye:

clip_image001

The article leads with:

The Obama administration on Friday unveiled data showing that many Americans with health insurance bought under the Affordable Care Act could face substantial price increases next year — in some cases as much as 20 percent.

Now, those are exchange premiums so they don’t apply to me.

Still, the headline was shocking enough to make me take a serious look at the premiums that I pay.

What I discovered is very interesting …

Why Right Brainers Will Rule the World …

November 14, 2014

Recently referenced in class a book called A whole New Mind: Why Right Brainers Will Rule the World.

As a hard core left-brainer, I figured I’d better pay attention to this one.

image

=====

Here’s the crux of the book …

The last few decades have belonged to a certain kind of person with a certain kind of mind — computer programmers who could crank code, lawyers who could craft contracts, MBAs who could crunch numbers.

But, the future belongs to a very different kind of person with a very different kind of mind — creators and empathizers, pattern recognizers, and meaning makers.

We are moving from an economy and a society built on the logical, linear, computerlike capabilities of the Information Age …

… to an economy and a society built on the inventive, empathic, big-picture capabilities of what’s rising in its place, the Conceptual Age.

Why the shift?

Because any kind of work that be reduced to repeatable rules and defined processes can be automated or shipped off-shore – even so-called knowledge work

Survival in the Conceptual Age requires thinking skills utilizing the right-side of the brain.

Specifically, “high concept” involves the capacity to:

  • detect patterns and opportunities
  • create artistic and emotional beauty
  • craft a satisfying narrative

…. and to combine seemingly unrelated ideas into something new and distinctive.

What’s required to to succeed in Conceptual Age?

Biases: The favorite-long shot bias …

November 12, 2014

In gambling and economics, there’s an observed phenomenon favorite-long shot bias.

image

Here’s how it works …

 

(more…)

This will take your breath away … guaranteed!

November 11, 2014

Even if you believe that “the end justifies the means”, this has gotta make your skin crawl.

Some background: Prof. Jonathan Gruber is an MIT economist who helped on RomneyCare in Massachusetts and was one of the primary architects of ObamaCare.

He was caught on video  speaking quite frankly about the crafting of ObamaCare.

His basic message:

“The bill was written in a tortured way … to be sure that the CBO didn’t score the mandate as a tax …  otherwise the bill would die … so, it was written to do that … with regards to the subsides … if people figured out that healthy pay in to give sick people money, it wouldn’t have passed … lack of transparency is a huge political advantage … and basically, call it the stupidity of the American voter or what … that was critical to getting the bill to pass … yeah, it would be better to be transparent, but I’d rather have this law than not.”

Watch the video … it’s even more chilling to hear Prof. Gruber say the words: Obfuscate and bank on American stupidity.

How do these guys sleep at night?

 

 

P.S. Another Gruber video will get wide play in the next couple of months.

He’s on tape saying that the specific language in the bill that only provided subsidies for folks going through state exchanges was intentional to motivate states to build exchanges,

Now, ObamaCare supporters are claiming it was just a typo that didn’t represent intent.

Well, the Supreme Court has signed on to settle the matter … with life & death consequence for ObamaCare.

This is gonna get interesting …

Dilemma: The case of the lost concert tickets …

November 10, 2014

 

A classic “framing” question from Kahneman’s Thinking Fast, Thinking Slow

Here’s the situation:

A woman has bought two $80 tickets to the theater.

When she arrives at the theater, she opens her wallet and discovers that the tickets are missing.

$80 tickets are still available at the box office.

Will she buy two more tickets to see the play?

Most (but, not all) survey respondents answer that the woman will go home without seeing the show.

Let’s try another situation …

Turnout: About the Dems’ highly touted GOTV ground game … and other ironic twists.

November 7, 2014

The United States Elections Project estimates that only 36.6% of eligible voters cast a ballot on Tuesday.

That’s pretty ironic since the Dems were, before the election, boasting about their predictive analytics and their unstoppable get-out-the-vote organization.

I haven’t been hearing much on the news about the GOTV machine that failed to get-out-the-vote.

So, what happened?  Here are a couple of hypotheses to ponder (more…)

Tuesday: A bad night for pollsters … and some other folks.

November 6, 2014

The election results looked a lot different than the pollsters predicted.

Pat Roberts was supposed to lose … he won by a comfortable margin.

Joni Ernst “might” eek out win … she romped.

Mark Warner was supposed to be popping champagne corks by 8 o’clock … he got less than 50% and the VA race hasn’t been officially called yet.

What happened?

Nate Silver’s 535 has nailed the symptoms … but not the cause.

Bottom line: Silver’s crew observes that there was an average 4-point polling bias in favor of the Dems ….

Another look: Is a college degree is worth it?

November 5, 2014

Lots has been written recently re: the economic value of a college degree.

Let’s boil it down to 3 key charts …

======

First, the cost side of the equation …

Sky-rocketing tuitions are loading students with an enormous amount of post-graduation debt.

While other forms of consumer debt have held relatively constant for the past 10 years, student loans have soared from “only” $200 million in 2004 to over $1 trillion today.

That’s the cost.

What about the benefits side?

Nate Silver has spoken …

November 4, 2014

Former darling of the left for having predicted President Obama’s hefty win over Mitt Romney, stats-jock Nate Silver has given his final pre-election prediction:

76% chance that the Republicans take control of the Senate today … with odds trending their way.

 

image

 

Silver’s prediction slides between the high-end Washington Post (97%) and CNN (95%) … and the low-balling New York Times (70%).

That means that there’s a 100% chance that Silver gets neither savant accolades, nor hoot-calls …  his prediction is stuck in the middle.

Maybe government does do some things right … (Did I really say that?)

November 4, 2014

Loyal readers know that I’m a small government guy … I’m with Reagan that government isn’t the solution, it’s usually the problem.

I think that the Federal government is collectively inefficient (i.e. bloated and wasteful) and, with increasing frequency, totally incompetent.

There are a couple of exceptions: the Military, the FBI, and — hold your hats on – the pre-Obama NASA

image
======

It used to be that I was pro-NASA and pro-space exploration because of emotion.

I can still remember being glued to the TV during the first moonwalk.

Even as a teenager, I felt a pang of excitement and national pride.

Later, I was able to rationalize the spending when I saw my older  brother selling stuff from the space program to commercial businesses.

Of course, last week’s incidents provided two additional rapid-fire proof points.

In praise of tough teachers …

November 3, 2014

My students are likely to cringe at this post which kinda legitimizes my teaching style.

Uh-oh …

=====

According to a recent WSJ article:

The latest findings in fields from music to math to medicine lead to a single, startling conclusion: It’s time to revive old-fashioned education.

Not just traditional but old-fashioned in the sense that so many of us knew as kids, with strict discipline and unyielding demands.

Why?

Because here’s the thing: It works.

image

Of course, that conclusion flies in the face of the kinder, gentler philosophy that has dominated American education over the past few decades.

The conventional wisdom holds that teachers are supposed to tease knowledge out of students, rather than pound it into their heads.

Projects and collaborative learning are applauded; traditional methods like lecturing and memorization — derided as “drill and kill” — are frowned upon, dismissed as a surefire way to suck young minds dry of creativity and motivation.

But the conventional wisdom is wrong.

And the following eight principles explain why …
